Therefore, GCD of numbers 395, 790, 49, 622 is 1

Given Input Data is 395, 790, 49, 622

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 395 is 5 x 79

Prime Factorization of 790 is 2 x 5 x 79

Prime Factorization of 49 is 7 x 7

Prime Factorization of 622 is 2 x 311

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(395, 790) = 790

GCD(395, 790) = ( 395 x 790 ) / 790

GCD(395, 790) = 312050 / 790

GCD(395, 790) = 395

Step2:

Here we consider the GCD from the above i.e. 395 as first number and the next as 49

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(395, 49) = 19355

GCD(395, 49) = ( 395 x 49 ) / 19355

GCD(395, 49) = 19355 / 19355

GCD(395, 49) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 622

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 622) = 622

GCD(1, 622) = ( 1 x 622 ) / 622

GCD(1, 622) = 622 / 622

GCD(1, 622) = 1

GCD of 395, 790, 49, 622 is 1
